"It will be understood that:- the rod 135, f .ex-

shaft Blfwhich theygear' drives isxniountedy tends loosely through the block 36 so that the arm 40 may move downwardly -from the position in which it is shown in Figs. 1, 3 and 4 without moving the rod 35. A spring 43, however, (or two springs as shown in the drawings tor better manufacturing reasons) surrounds the rod 35 and extends from its lower to the block 36 so that the arm 40 in moving` downwardly, as above suggested, slightly compresses the spring 43. The spring, however, is very long and its Atension is only slightly increased by this downward movement of the arm 40 and as the throttle valve 17 moves very easily in the intake pipe, the tension of the spring is sufficient to move the arm 40 upwardly unless other forces intervene. Thus it will be seen that the manually operated rod 28 may readily position the valve 17 unless the latter is set by the governor as hereinafter described.

It will be seen also that the spring device 43 above described will act to yieldingly retain the throttle valve 17 in open position as long as the manually operated device 28 is in the position shown in the drawings.

The governor 29 above referred to is retained in its inoperative position by a spring 44 which is adjustable as by a socket nut 45. The spring 44 bears against a block 46, which in turn bears against the end 47 of the rod 33 above described. The block 46 has trunnions 48 for one of the arms of a bell crank lever 49, the other arm of which is connected to a rod 50 which extends upwardly to the arm 40 of the throttle valve to which arm it is connected as is the rod 35, except that there is no spring surround-- ing the rod 50. Thus the rod 50 extends through a block 51 which is trunnioned in the arm 40 in the samel manner as is the block 36 above described, and a nut 52 and lock nut 53 provide adjustment for the rod 50 relative to the arm 40. rllhe block 51 is pivoted in the arm 40 somewhat nearer the shaft 41 so that a `lesser movement of the rod 50 is required to operate the throttle valve. rlhe arm 40 has a rigid stop 54 for determining the open position of the throttle valve, and an adjustable stop 55 determines the closed position so that it may be set for idling the motor.

It will be understood that the governor' connections to the throttle valve permit of the arm 40 being moved downwardly from the position shown in Figs. 1, 3 and 4 without moving the rod 50, as when the manually operated device closes the throttle. Also, the governor may through these connections close the throttle valve against the action of the spring device 43 without moving the rod 35, that is, without shitting the manual control.

The above connections permit the gov- -ernor to absolutely control the speed ofg the motor, except that the manual control may close the throttle more than it is tor the time being closed by the governor connections. In other words, manual control limited to control of the motor below the speed determined by the governor.

@t course the above statement is qualified to the extent that the spring device 43 may affect the action of the governor but because of the use of a very long spring as shown, there is no practical effect produced upon the action ot the governor by moving the bell crank lever 34 from one ot its extreme positions to the other.

The arm 40 and the upper ends of the rods 35 and 50 are enclosed in a easing 5G and its cover 57. The bell cranks 34 and 49 and associated parts are enclosed in a casing 58 shown as mounted upon an extension 59 of the crank case 11. A tube 60 connects the casings 56 and 58 and encases the rods 35 and 50 so that all of these parts are enclosed, thus preventing tampering with the governor and the adjustments.

While I have herein described in some detail a specific embodiment of my invention, which I deem vto be new and advantageous and may specifically claim, I do not desire to be understood that my invention is limited to the exact details of the construction, as it will be apparent that changes may be made therein without departure from the spirit or scope of my invention.

Having thus described my invention, what I desire and claim by Letters Patent 1s:

1. In a hydrocarbon motor having a throttle valve, the combination of manual means adapted to positively close the throttle valve including a sliding connection, spring means associated with the sliding connection to yieldingly retain the throttle valve in open position, and governor operated means to determine the maximum opening of said throttle valve.

2. In a hydrocarbon motor, the combination with the intake conduit and a throttle valve therein, of a manually operated rod,

a sliding connection between the rod and said throttle valve so that it will move the throttle valve positively in one direction, a spring on said rod to yieldingly retain the valve in its open position, and a governor operated rod connected to said throttle valve to positively move it from open to closed position against said spring.

3. In a hydrocarbon motor, the combination with the throttle valve thereof, ot a manually operated rod having a sliding connection to said throttle valve to positively move the valve towards closed position and yieldingly move the valve towards open position, and a governor operated device connected to said throttle valve to move said valve towards closed position 'lll in opposition to the yielding means of said y manually operated connections.

l. In a hydrocarbon motor, the combination with the intake conduit and the throttle valve therein, of manually operated means for moving said throttle valve, connections from said means to said throttle valve to cause positive closing of the throttle valve by one movement of said means and yie1d- 1U ino' o eninfr of said valve lo the o osite movement of said means, a governor operated by the motor, and connections from said governor to said throttle valve to positively move the throttle valve towards closing position against the yielding part of said connections.

In testimony whereof I a-x my signature.
